Fixes#407 (partially) and #441
Description of the changes:
Remove TitleBarHelper and all <Border x:Name="CustomTitleBar" />
Let the system defines the draggable region
Centralize all events and functions associated to the title bar in a single control TitleBar instead of code splitted between MainPage/TitleBar/HistoryList/Memory.
Use the standard title bar when high contrast is activated instead of the custom one.
Modify the color of the title when the window doesn't have focus
Fix the right padding of the title bar with high contrast
How changes were validated:
Manually tested with LtR and RtL languages
Manually tested with high contrast
Tested when History and Memory flyout are opened
Fixes#402 and #414
Divide by 4 the CPU usage of OverflowTextBlock when buttons are pressed very quickly.
Description of the changes:
Xaml-side:
OverflowTextBlock has some performance issues:
double scrollviewer: the listview was in a scrollviewer, while the control already containing one -> it breaks the virtualization of the listview and impacts on UI performance.
The listview used a StackPanel, this panel doesn't support virtualization of ListViewItems contrary to ItemsStackPanel
No ListView-specific features were used, an ItemsControl is more efficient and lighter.
refactor how we manage the visibility of the left/right buttons in OverflowTextBlock, the new version is more reactive and will not display the right arrow when not necessary (see GIF below).
remove the ItemContainerSelector ExpressionItemContainerStyle, not really used by OverflowTextBlock
remove UI glitches generated by ChangeView when users type fast (control partially hidden and scrolling issues, see the GIF below).
only modify the accessibility view when it's necessary
ViewModel-side:
stop fully refreshing ExpressionTokens in StandardCalculatorViewModel when a new command were sent, instead, use a IObservableVector to only send new tokens to the UI (in average only 1 or 2 UI items are refreshed while the full expression was refreshed before)
How changes were validated:
Manually
* Modify the height of RowDltrUnits when UnitConverter is in LandscapeLayout mode
* clean
* Use the same layout than the existing one while fixing the issue
* Refactor SupplementaryItemsControl to improve performance, not rely on parents and not force the parent element to be HorizonAlignment="stretch"
* take feedback into account
* add HorizontalNoOverflowStackPanel to vcproj.filters
* format conditionals
* replace max by std::max
The .resw files for all languages are expected to be checked into the repo (this used to not the the case). Let's remove the conditions in the project file which ignore them if they don't exist.
Additionally removes pseudo-loc resource references from the build as pseudo-loc resources aren't currently being generated.
Update the Microsoft.UI.Xaml NuGet package to a new version. The ARM64 framework package in 2.0.181018003.1 had entries missing from its manifest, so the classes in the package couldn't be activated.
The app currently logs diagnostic events to ETW in various places. If we add certain flags to those events, the data is eligible to be sent as telemetry. (Whether it actually gets sent is controlled outside of Calculator--for example, there are lots of checks at the system level to ensure privacy settings are honored.)
Currently we set the "eligible for telemetry" flags only in official builds, so no telemetry gets uploaded while the app is in development. We already have this set up for the main TraceLogging provider, but we also need to do this for the AppLifecycle performance logging.
Calculator (the main app project) depends on CalcManager, but only transitively: Calculator -> CalcViewModel -> CalcManager.
However, Calculator's project file currently has a direct dependency on CalcManager. Let's remove this to make it harder to accidentally introduce new dependencies between the layers.
Also cleaning up some commented-out directives in the CalcManager MSBuild file.
Remove LayoutAwarePage, SuspensionManager, and other suspend-resume handling code. SuspensionManager::SaveAsync and related methods weren't actually called anywhere. I didn't attempt to remove the serialize/deserialize code at the ViewModel layer, although much of that is likely not needed either.
We may decide we want to persist more state through a suspend-terminate-resume cycle (as the app might have done a long time ago). But if we decide we want that, we should not use a persistence mechanism that's closely coupled to frame navigation.
